Seprify and BIOGRUND develop titanium dioxide-free tablet coating for nutraceuticals

Swiss ingredients developer Seprify and BIOGRUND, a manufacturer of powder premixes for film coatings, have launched a mineral-free tablet coating solution for the nutraceutical market.

Designed as a clean-label alternative to whitening agents such as titanium dioxide (TiO₂) and calcium carbonate, the ready-made formulation integrates Seprify’s plant-based cellulose ingredient, SilvaAlba.

The coating solution is designed to achieve the bright white appearance and processing stability traditionally provided by titanium dioxide (E171) or calcium carbonate (E170) while supporting clean-label formulation strategies with fewer ingredients. Compared with commonly used mineral alternatives, the coating is claimed to improve pH stability, which can help maintain performance across typical nutraceutical processing conditions.

As a form of microcrystalline cellulose, the ingredient also provides regulatory familiarity for manufacturers and formulators, while Seprify’s scalable production approach can also help to ensure a reliable supply as demand for TiO₂ alternatives grows. Together, these properties enable the coating system to deliver the appearance, processing reliability and formulation simplicity required by nutraceutical manufacturers.

The mineral-free coating system is now available for user evaluation and formulation trials, with BIOGRUND providing customised coating solutions tailored to specific tablet formulations. It will be on show at Making Pharmaceuticals & Nutraceuticals (21–22 April) and Vitafoods Europe (5–7 May).
